SPECIFICATION forming part of Letters Patent No. 748,868, dated January 5, 1904.

Original application filed June 18, 1903, SerialiNo. 162,006. 110.171,638.

To all whom t may concern:

Be it known that I, JOHN HOEY, a citizen of the United States, residing in the city and county of San Francisco and State of California, have invented new and useful Improvements in Bed or Couch Bottoms, ofv which the following is a specification, this application being a division of my application, Serial No. 162,006, tiled June 18, 1903.

My invention relates to improvements in bed and couch bottoms in which an elastic cable or wire support for the upper mattress is attached to a framework, which framework, usually termed the bed-bottom, is supported upon the bedstead.

My invention consists of parts, construe-- tions, and combinations, as hereinafter described.

Referring to the accompanying drawings, Figure 1 is a bottom View showing the attachment of the cables and adjusting devices. Fig. 2 is a transverse sectionon line a: :not Fig. 1. Fig. 3 is a perspective view of the elastic strengthening and adjusting bar. Fig. 4 shows the application to an adjustable frame.

Bed and couch bottoms are usually madeby stretching elastic cables or a Woven-Wire fabric across a rigid supporting-frame. In all such structures considerable difficulty arises from the tendency of the central portion to be unduly'depre'ssed and the unsupported sides or edges of the fabric to be drawn toward each other by continual use.

It is the object of my invention to stiden and strengthen such fabric and to maintain the edges in their proper position, also to pro- ,vide a means for regulating the tension where the fabric is composed of elastic cables eX- tending across the frame upon which they are supported.

A represents the side and B the end rails of a mattress or couch frame bolted together at the angles and constructed in any suitable or desired manner for the attachment of the wire cables 6,*which are stretched across between the end bars of the frame. These cables may either be employed in conjunction with a woven-wire fabric 2, which is also attached to the frame and superposed upon the vof these transverse bars. mediate bars (marked 3) are permanently at- Dividedy and this application tiled September 2, 1903. Serial (No model.)

cables, or the cables may be so numerous that in conjunction with my attachments they will form a sufticient support without the use of the fabric. The cables 6 are attached t0 the end bars B, as shown.

3 represents metal stripsA or bars of some Width and sufficiently thin so that while comparatively rigid they are very elastic. These bars are bent so as to form curved loops tat intervals, and' the outer ends of the bars are also bent or curved, as shown. In the construction of the mattress vlI may employ tive The three intertached to the edges of the fabric, and. the bars 3, which are nearest the ends, are slidable upon guides, so as to be moved to or from the ends. These guides may take the form of cables extending'beneath the edges of the woven-,wire fabric, as at '7, or other suitable or desired form.

The elastic cables 6 are secured at the ends beneath the woven-Wire fabric and may rst extend in parallel lines from one end to the other, as many being employed as may be found desirable or efficient. l then draw these cables together in pairs from each end, and the first and second from either side may be dropped into the loop 4 of the cross-bar, which is substantially midway between the two cables. The third and fourth, fifth and sixth, and so on, are similarly drawn into the loops which correspond with their positions in the bars 3a, which are nearest to the ends. From 'this point to the next bars 3 the two cables are shown as lying close together and parallel. Passing through the loopsof the second bar from the end they are then diverted and the cables 1 and 2 are separated and droppedinto the loops of the central bar. 3 and 4: are likewise separated, 3' lying in the same loop with 2', and so on' across the frame, thus forming the elastic cables into elongated diamond shapes hetween the center bar and the -two adjacent ones on veach side. This arrangement of the cables provides for a sufficient increase of tension and maintaining of the cables. in closecontact with the woven fabric, so that whatever elastic quality there may be in the ICO two parts operates very closely in unison to form an elastic support for any superstruc- V ture which may be placed thereon.

It will be seen that various arrangements of the elastic cables may be made by crossing them in different ways, and almost any conguration of the cables may be made between their ends by stretching them in dierent Ways and securing them in the loops 4 of the various bars. lf the tension of the cables becomes too much reduced, it is easily increased by sliding the end bars 32L farther toward the ends, and this, acting through the convergent end portions of the cables, will increase the tension throughout, since the cables are easily slidable within the loops of the cross-bars. If it be found desirable to use the cables alone without woven-wire fabric, it will be seen that the number of cables may be increased, and the number of loops and elastic transverse bars correspondingly increased, or the cables may be stretched so as to cross each other at different points, and thus form a complete elastic bed bottom without any woven-wire superstructure.

It will beunderstood that my invention is equally applicable to couch or bed bottoms in which one end of the fabric is secured to a tension adjusting bar movable with relation to the main frame, as shown in ligure 4.

Having thus described my invention, what Iclaim, and desire to secure by Letters Patent, is-

1. The combination in a bed or couch bottom of a rigid frame, an elastic fabric stretched from end to end thereof having transverse elastic bars with curved loops at intervals between the euds,elastic cables having their ends fixed to the ends of the frame and their intermediate portions engaging the loops of the transverse bars.

2. The combination in a bed or couch bottom of a rigid` frame, an elastic fabric stretched from end to end thereof, elastic transverse bars having curved loops, elastic cables extending from end to end of the frame,other transverse bars having loops slidable upon the cables, said cables drawn together or separated diagonally in pairs and laid in the loops to maintain their position,

the slidable bars serving to regulate the ten-l sion of the cables by moving toward or from the ends of the frame.`

3. The combination in a bed or couch bottom of a rigid frame, elastic cables attached to and extending` across the frame, elastic continuous bars having loops formed at intervals between their ends, one or more of said bars movable in a direction substantially lengthwise of the cables, said cables 6o
